Sažetak
The coordination chemistry of molybdenum has been growing rapidly due to the rich biochemical and catalytical properties of the obtained complexes [1, 2]. Molybdenum Schiff’s base complexes are of particular interest because MoO2L type of complexes possess open coordination site that can be utilized for substrate binding properties [3]. Furthermore, hydrazone ligands are the most important pharmacophoric cores of several anti- inflammatory, antinociceptive, and antiplatelet drugs [4]. In light of the mentioned, two ligands obtained from nitrobenzaldehyde were prepared and coordinated to the MoO22+ core. If the reactions were performed in alcohols, mononuclear complexes, [MoO2(L1or2)(D)], D=donor molecule, were obateined. When acetonitrile was used as the solvent, the polynuclear [MoO2(L1)]n or mononuclear complex [MoO2(L2)(H2O)] was obtained. All the complexes were analysed and identified by IR-ATR, TG analysis, while molecular and crystal structure was determined by X-Ray diffraction. It has been noticed that grinding of [MoO2(L2)(D)] alters the crystal structure and obtained compounds correspond to [MoO2(L2)]n. After exposure to alcohol vapors, the starting compounds [MoO2(L2)(D)] were obtained. Further research perspective is to test the obtained complexes as the catalysts in the oxidation reactions following the principles of green chemistry.
